specification of Letters raient. 'Patented July 23, 1914 Application filed March 11, 1913. Serial No. 753,519. l y

To all Lol-10m 'it may concern.'

Be it known that I, AMos J. Coovnn, a citi- Zen of the United States of America, and a resident of the city of Seattle, in the county of King and State of lVashington, have invented certain new and useful Improvements in Stump-Burners, of which the following is a specification.

My invention has for one of its objects the provision of a simplified and improved construction of the above type wherein the fire is maintained at the base of the stump in an efficient manner.

Other objects will be set forth as my description `progresses and those features of construction, arrangements and combinationsof parts on which I desire protection succinctly defined in my annexed claims.

Referring to the accompanying drawing wherein like numerals of reference indicate like parts throughout: Figure 1 is a view, partly in elevation and partly in section, of my invention as in use, the draft appliance being used in conjunction with the hood. Fig. 2 is a top plan with portions broken away, and Fig, 3 is a perspective of the hood removed, a portion of the sand ring being broken away.

My improved hood 1 which is open at top and bottom and adapted to be placed around the stump, is substantially frusto-conical in form and composed of opposite vertical metallic sections which are sufficiently pliable to enable'the normally lapped vertical side edge portions of one section (see Fig. 2) sliding within the other section as may be required to bring the'upper yedge portion of the hood into snug relation to the stump.

While other means may be employed for holding the component hood sections in roper relation, a convenient device consists of a flexible tie member or cable 2 which is fixed to an eye 3 and passed around thehood g as 5, and thon, after having been drawn tightly, to press the upper end portions of the hood sec` tions firmly together and .against the stump, secured, asto a cleat 4. Eye 3 and cleat zlare provided on the adjacent side portions of respective sections of the hood.

Reference numeral 7 indicates a ring or annulus which can be employed in conjunction with hood 1 when desired, the same having a fiaring upper portion 7 adapted to support suitable packing material 8, as for example, soil taken from about the roots of the stump. Ring'', which like hood 1 is formed of comparatively flexible metallic sections having lapped end portions so that one can slide freely on the other, has its lower portion 7 iiaring downwardly and normally bearing against the inner face of the hood. Said ring is therefore substantially V-shaped in vertical section and the concave side thereof is normally arranged o utwardly and receives the upper edge portions of the hood sections so as to be held by the latter and pressed against thea stump` l when tie member 2 is applied.

My draft appliance comprises an air intaljre tube 10 and an outlet tubell, the latter being connected to a stack or vent pipe l2 which is fitted in a groove in the stump and extends through the upper end of the hood.`

Hood 1 is formed with an air inlet conduit or port 14 which normally telescopes tube 10..

Tubes v10 and 11 are formed integral with one another, being conveniently connected by a web15 and provided with a fixed ta` pered deflector 16, thelatter of which projects from the inner ends of said tubes, with its thin end portion arranged innermost.

Reference numeral 20 indicates rn opening closed by a suitable sliding door 21, and through which solid fuel can be fed or air admitted to the hood as may bo desired.

In practice, a suitable cavity, as 30, is first provided in the stump and a fire started in any suitable manner following which my improved draft appliance is inserted, and then the hood 1 applied, as hercinbefore set forth.'

A longitudinal cavity leading from cavity 30 is provided for the reception of pipe 12.

Having thus described my invention what I claim as new, and desire to secure by Letters Patent of the United States of America, isz- 1. A stump burner comprising a hood adapted to be placed about the stump, said hood comprising vertically arranged sections overlapping at their side edges, and flexible means for drawing the upper edge portions of said hood sections firmly against the stump.l

2. A stump burner comprising a hood comprising vertically disposed tapering sections one having its vertical side edge portions overlapping the side edges of the other section, and a exible tie member normally passing around said hood for holding its adapted to be placed about a stump, and supporting means extending around the upper edge portion of said hoodfor holding a paoklng means against the stump.

4. A stump burner comprising a hood adapted to be laced about a stump, and a removable pac (ing supporting ring at the upper` portion of said hood igor holding a packing means against the stump.

5. A stump burner comprising a hood adapted to be placed about a stump, and a packing support at the upper portion of said y hood formed of overlapping sections for holding a 6. A stump burner comprising a hood adapted to be placed about a stump, and a removable packing ring adapted to engage the stump and having a Haring uppei` porpacking means against the stump.
